Token Authorization Django {"detail":"Authentication credentials were not provided."} - django

Question

I am trying to implement Token based Authorization at my server APIs. But, when I fire a query then it returns {"detail": "Authentication credentials were not provided."}
I have done almost all the settings recommended at various posts and also at the Django documentation.
In my settings.py:
INSTALLED_APPS = [
'rest_framework.authtoken',
]
And also,
REST_FRAMEWORK = {
'DEFAULT_AUTHENTICATION_CLASSES': (
'rest_framework.authentication.TokenAuthentication',
),
'DEFAULT_PERMISSION_CLASSES': (
'rest_framework.permissions.IsAuthenticated',
),
}
In my views file:
from rest_framework.authentication import TokenAuthentication
from rest_framework.permissions import IsAuthenticated
class UserList(generics.ListCreateAPIView):
queryset = User.objects.all()
serializer_class = UserSerializer
authentication_classes = [TokenAuthentication]
permission_classes = [IsAuthenticated]
And in my Apache Config file at WSGI
WSGIPassAuthorization On
RewriteEngine on
RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule .* - [e=HTTP-AUTHORIZATION:%1]
I don't know if I am missing anything other than this. The token is pre-generated at super user level using command line.

Answer 1

The default Django Rest Framework HTML that you see when you go to your website in the browser does not work with token authorization. This is because you need to put Authorization: Token <insert your token here> in your header when sending a request. This is an issue because the form you fill out has no place to change headers.
I would suggest either Postman (nice GUI), or curl (command) to test out your API since you need to edit the HTTP headers of your requests.

Have you seen this related S.O. question?
If you're using mod_wsgi, leave out the REWRITE section, put WSGIPassAuthorization On below the WSGIScriptAlias, WSGIDaemonProcess and WSGIProcessGroup directives. Just got my Apache + mod_wsgi configuration working, looks something like this:
...
WSGIScriptAlias / /var/www/html/base/wsgi.py
WSGIDaemonProcess django_app python-path=/var/www/html python-home=/var/www/html/env
WSGIProcessGroup django_app
WSGIPassAuthorization On
